Abstract

Background

We aimed to clarify the appropriate timing for performing percutaneous transhepatic gallbladder drainage (PTGBD) and cholecystectomy, and the effect of PTGBD on surgical difficulty in acute cholecystitis patients.

Methods

We retrospectively examined 46 patients who underwent laparoscopic cholecystectomy (LC) after PTGBD for acute cholecystitis. We evaluated the duration from acute cholecystitis onset to PTGBD and the appropriate interval from PTGBD to elective LC. Intraoperative blood loss, operating time, rate of conversion to open surgery, and rate of severe adhesion were the objective and subjective measures.

Results

Based on the cut-off value calculated using the Youden index, the group with a duration from acute cholecystitis onset to PTGBD of ≤73.5 h had a significantly shorter operating time (127.5 min vs. 180.0 min, P = 0.007), lower rate of severe adhesion (3/20 vs. 14/26, P = 0.007), and lower rate of conversion to open surgery (2/20 vs. 13/26, P = 0.004); moreover, the interval from PTGBD to elective LC did not significantly differ between these groups.

Conclusion

The most important predictor of successful LC following PTGBD for acute cholecystitis was a duration from acute cholecystitis onset to PTGBD of ≤73.5 h. Hence, PTGBD should be performed immediately in cases where early cholecystectomy is not indicated.

Highlight

Yamada and colleagues are the first to show that the most important predictor of successful laparoscopic cholecystectomy after percutaneous transhepatic gallbladder drainage (PTGBD) is not the timing of cholecystectomy following PTGBD, which has been the focus of most studies, but instead the duration from onset of acute cholecystitis to PTGBD.
